Installing EnviroSCAN, EnviroSMART & Diviner 2000 access tubes

16. Auger ahead of the access tube by approximately 10 – 20 cm (4 – 8 inches). Alternate

between augering and hammering until the dolly resting on top of the access tube nearly

touches the top of the tripod.

17. Insert the yellow Nylon dolly (which has the same diameter as the access tube) into the

access tube and continue hammering and augering until the mark on the dolly is level with

the top of the tripod.

Note: Installing the access tube to this depth will enable the base of the

top cap to sit flush with the ground. This will position the middle of the

first sensor at 10 cm below the ground surface. Sometimes it may be

desirable to position the first sensor 5 cm below the ground surface. If

this is the case, only hammer in the yellow nylon dolly until the mark on

the dolly is 5 cm above the top of the tripod.

18. Auger out the remaining soil from inside the access tube.

19. Remove the tripod pins by inserting the Tommy bars into the holes of the tripod pins and

pulling them upwards with a twisting motion.
